Abstract
Description
Technical Field
[0001] This invention relates to the technical field of T-beam reinforcement cage processing equipment, and in particular to a material placing trolley for processing T-beam reinforcement cages. Background Technology
[0002] In modern bridge engineering, T-beams are widely used in highway, railway, and municipal bridge construction due to their significant advantages such as reasonable structural stress, strong span capacity, and convenient construction. Especially in the superstructure of long-span bridges, the quality of T-beams directly affects the overall load-bearing safety and service life of the bridge. The steel reinforcement cage, as the "skeleton" of the T-beam, is of paramount importance in terms of its processing quality. Precise control of parameters such as the specifications, density, and spatial position of the steel reinforcement not only affects the bending and shear strength of the T-beam but also closely relates to the bond strength of the concrete and the durability of the structure. In actual construction, the processing of the steel reinforcement cage involves multiple processes, including steel cutting, bending, binding, and welding. Among these, the concrete placing trolley, as a key piece of equipment for precise positioning and orderly transfer of the steel reinforcement cage, directly determines the processing efficiency and accuracy of the steel reinforcement cage, significantly impacting the smooth progress of subsequent T-beam formwork installation and concrete pouring. Existing concrete placing trolleys for T-beam reinforcement cage fabrication have provided certain equipment support for the mass production of T-beams in long-term engineering practice. However, with the continuous improvement of bridge engineering's quality requirements for T-beams and the diversification of T-beam specifications, some aspects requiring improvement have gradually emerged in practical applications. Regarding equipment adaptability, the load-bearing frame and related positioning components of most placing trolleys have relatively fixed dimensions. When dealing with T-beam reinforcement cages of different spans and reinforcement designs, significant modifications or direct replacement of the equipment are often required. This increases equipment operating costs and reduces production continuity to some extent.
[0003] Therefore, it is necessary to provide a fabrication trolley for processing T-beam reinforcement cages to solve the above-mentioned technical problems. Summary of the Invention

The square fabric rack includes a main square tube placed directly on the top roller area of the roller frame. A secondary square tube is set directly above the main square tube. The main square tube and the secondary square tube are fixed horizontally and vertically by welding crossbars and vertical bars, respectively. Slide rails are installed at equal intervals on the top plane of the secondary square tube. A sliding sleeve is installed on the top of the slide rail. The sliding sleeve can slide relative to the slide rail and has damping. A U-shaped steel block is fixedly installed on the vertical surface of the sliding sleeve on the same side. The top of the U-shaped steel block has a convex groove along the vertical direction, and the inner sidewall of the convex groove has a limit groove at equal intervals. A positioning plate is fixedly installed on the outer wall of the crossbar at the top position. A base plate is welded to the top of the positioning plates in the same row. A base groove is opened on the top of the two base plates and on the same vertical plane as the limiting groove.
[0006] Preferably, the cross-section of the base groove is V-shaped, and the groove wall is provided with anti-slip texture.
[0007] Preferably, the slide rail has an insertion hole on its inner side, a synchronizing block is inserted into the insertion hole, and the synchronizing block is fixedly connected to the slide sleeve. A C-shaped plate is fixedly connected to the end of the synchronizing block. Shaft seats are symmetrically installed on the top of the main square tube at both ends. A support rod is symmetrically installed between the two shaft seats on either side. A first gear shaft is installed on the support rod through a fixing member, and the fixing member is connected to the end of the C-shaped plate. A lead screw is symmetrically installed between the two main square tubes. The two lead screws are arranged parallel to each other on both sides of the first gear shaft and mesh with it. The threads on both sides of the lead screw have opposite directions with the center line as the dividing line. A control motor for driving the lead screw rotation is fixedly installed on the outer side of the main square tube.
[0008] Preferably, an I-beam is slidably installed in any of the convex grooves. Square holes are equally spaced on the opposite surfaces of the I-beams along their paths. Locking bolts for positioning are provided on the I-beams. Synchronous gear blocks are equally spaced on the opposite surfaces of the two I-beams in the same U-shaped steel block near their ends. Synchronous gears are meshed between the two synchronous gear blocks on the same side. The synchronous gears are fixed to the inside of the U-shaped steel block by a positioning shaft.
[0009] Preferably, a roller is installed on the inner side of the limiting groove, and the outer ring of the roller contacts but is not connected to the inner wall of the I-beam.
[0010] Preferably, the fixing component includes a displacement seat that is slidably mounted on the support rod. A second gear shaft is installed inside the displacement seat through a sleeve, and the second gear shaft is concentrically and fixedly connected to the first gear shaft. An adjustment frame is inserted into the displacement seat. A linkage tooth block is provided on the inner side wall of the adjustment frame, and the linkage tooth block meshes with the second gear shaft. A connecting rod is fixedly installed on the upper end face of the adjustment frame, and the end of the connecting rod is fixed to the lower end face of the I-beam.
[0011] Preferably, silicone blocks are embedded in the center of both ends of the main square tube and the secondary square tube, and the outer surface of the silicone blocks is provided with corrugated grooves.
[0012] Preferably, a silicone fin is embedded in the center of the inner sidewall of the square hole.
[0013] Compared with related technologies, the concrete placing trolley for processing T-beam reinforcement cages provided by the present invention has the following beneficial effects: This invention provides a placing trolley for processing T-beam reinforcement cages. The invention includes components such as U-shaped steel blocks. Within the same U-shaped steel block, synchronous gear blocks are evenly spaced on opposite faces of two I-beams near their ends. A synchronous gear meshes between the two synchronous gear blocks on the same side. The synchronous gear is fixed to the inside of the U-shaped steel block via a positioning shaft. During operation, the I-beams can be adjusted by loosening the locking bolts. When one I-beam slides within a convex groove, the synchronous gear block inside that I-beam rotates the synchronous gear. The rotated synchronous gear then drives the other I-beam to slide within the convex groove. The sliding directions of the two I-beams relative to the convex groove are opposite. Therefore, compared to the initial state, the square holes on the two I-beams change from a fully overlapping state to a partially overlapping state, allowing for the reduction of the rebar diameter and thus satisfying the positioning and fixing of rebars of different sizes without requiring overall replacement, further expanding the applicability.
[0014] This invention provides a fabrication trolley for processing T-beam steel reinforcement cages. An adjusting frame is inserted into a displacement seat. The inner wall of the adjusting frame is equipped with a linkage tooth block, which meshes with a second gear shaft. A connecting rod is fixedly installed on the upper end face of the adjusting frame, and the end of the connecting rod is fixed to the lower end face of an I-beam. When the first gear shaft rotates, it synchronously drives the second gear shaft to rotate within the sleeve. The second gear shaft, after rotating, gradually meshes with the linkage tooth block, thereby causing the adjusting frame to move laterally on the displacement seat. The movement of the adjusting frame then drives the connecting rod to move synchronously, which in turn drives the I-beam to move, thus adjusting the overlapping area of the square holes on the I-beam. This method allows for adjustment of positioning dimensions at different positions by changing the forward and reverse rotation of the same drive source, resulting in higher control precision and further improved adjustment convenience.

Detailed Implementation
[0016] To make the technical means, creative features, objectives and effects of the present invention easier to understand, the present invention will be further described below in conjunction with specific embodiments.
[0017] Furthermore, the terms used below are defined based on the functionality of this invention and may vary depending on the user's, operator's, or conventions. Therefore, these terms are defined based on the entire contents of this specification.
[0018] Please see Figures 1-7 The present invention provides a material placing trolley for processing T-beam steel reinforcement cages, which includes a support rail 1. The support rail 1 is arranged in parallel on the working ground, and the length of the support rail 1 is determined according to the total length of the T-beam steel reinforcement cage production line. The length of the support rail 1 is generally no more than five meters. Adjacent support rails 1 are fixed together by rivets or high-strength steel bolts. The support rail 1 is made of Q235B steel. A sealing gasket is provided at the connection of adjacent support rails 1. Roller frames 11 are evenly spaced on the top of the support rail 1. Some roller frames 11 are driven to rotate by a drive motor 12. A square fabric rack 2 is provided at the top roller position of the roller frame 11. The square fabric rack 2 includes a main square tube 21 placed directly on the top roller area of the roller rack 11, and a secondary square tube 22 is provided directly above the main square tube 21. The main square tube 21 and the secondary square tube 22 have the same length, and neither of them exceeds four meters. like Figure 7As shown, the processing flow of the T-beam steel reinforcement skeleton is as follows: coiling the reinforcement, adjusting and shaping it with a shearing and bending machine, placing it into the welding platform by a grabbing and placing robot, welding it with the reinforcing bars, and placing it into the material placement trolley by the grabbing and placing robot. Therefore, the square material placement frame 2 is generally located on one side of the grabbing and placing robot in the production line. After several steel reinforcement skeletons have been placed on the square material placement frame 2, the drive motor 12 can be started to drive the steel reinforcement skeleton to the next welding station. The main square tube 21 and the secondary square tube 22 are fixed horizontally and vertically by welding with crossbar 23 and verticalbar 24 respectively. Both the main square tube 21 and the secondary square tube 22 are made of high-strength aluminum alloy with a wall thickness of 8-10mm. The welding is carried out by carbon dioxide gas shielded welding and stress relief treatment is performed after welding. The top plane of the secondary square tube 22 is equipped with slide rails 25 at equal intervals, and a sliding sleeve 26 is installed on the top of the slide rail 25. A U-shaped steel block 3 is fixedly installed on the vertical surface of the sliding sleeve 26 on the same side. The spacing between the two U-shaped steel blocks 3 is the placement size of the steel reinforcement cage. The sliding sleeve 26 can slide relative to the slide rail 25 and has damping. Steel reinforcement cages of different sizes can be adjusted by pushing the position of the sliding sleeve 26 relative to the slide rail 25. The top of the U-shaped steel block 3 has a convex groove 31 in the vertical direction. The inner side wall of the convex groove 31 has a limit groove 32 at equal intervals. In this state, the two U-shaped steel blocks 3 form a placement position between the two limit grooves 32. The grabbing and placing machine moves the steel reinforcement skeleton horizontally to the top of the placement position. Then the grabbing and placing machine controls the steel reinforcement skeleton to descend vertically along the limit groove 32. A positioning plate 4 is fixedly installed on the outer wall of the crossbar 23 at the top position. A base plate 41 is welded to the top of the positioning plates 4 in the same row. A base groove 42 is opened on the top of the two base plates 41 and on the same vertical plane as the limiting groove 32. After the material grabbing machine controls the steel reinforcement skeleton to descend vertically along the limiting groove 32 to a certain height, the bottom of the steel reinforcement skeleton will enter the base groove 42 at the top of the base plate 41 and abut against the bottom of the base groove 42. The base groove 42 provides bottom support for the steel reinforcement skeleton. As described above, once the bottom of the fabric grabbing machine contacts the base groove 42, the placement of a single rebar cage can be completed. Similarly, all the placement positions are filled with rebar cages. The square fabric rack 2 can be assembled and arranged according to the actual T-beam size. For example, different numbers of square fabric racks 2 can be installed on the support rail 1. The lengths of the different numbers of square fabric racks 2 can be the same or different. For example, all of them are four meters long or some are less than four meters long. After assembly, the number of the above-mentioned placement positions on the same support rail 1 increases, thereby adapting to the processing needs of beam-type skeletons of different lengths, which ensures higher production flexibility. To prevent hard contact between multiple square fabric racks 2, silicone blocks 211 are embedded in the center of both ends of the main square tube 21 and the secondary square tube 22. The outer surface of the silicone blocks 211 is provided with corrugated grooves. When two adjacent square fabric racks 2 work in parallel, the two silicone blocks 211 make flexible contact, which will not damage the ends of the main square tube 21 and the secondary square tube 22.
[0019] In another embodiment, the cross-section of the base groove 42 is V-shaped. The width of the V-shaped base groove 42 gradually increases from bottom to top. When steel reinforcement cages of different sizes are placed in the base groove 42, they can all abut against the inner wall of the base groove 42, ensuring support while also having universality. Meanwhile, anti-slip textures are provided on the groove wall of the base groove 42 to increase the contact friction between the bottom area of the steel reinforcement skeleton and the base groove 42, making it less likely for the two to wobble relative to each other at the contact point.
[0020] See Figures 1-6 In another embodiment, the slide rail 25 has an insertion hole 251 on its inner side, and a synchronization block 252 is inserted into the insertion hole 251. Generally, the slide rail 25 with the insertion hole 251 is located at both ends of the sub-square tube 22, and the slide rail 25 at other positions may not have the insertion hole 251, thereby reducing the manufacturing cost of the device. Furthermore, the synchronizing block 252 is fixedly connected to the sliding sleeve 26, and a C-shaped plate 253 is fixedly connected to the end of the synchronizing block 252. The C-shaped plate 253 can drive the synchronizing block 252 to move within the socket 251. After the synchronizing block 252 moves, it synchronously drives the sliding sleeve 26 to move on the slide rail 25. The top of the main square tube 21 is symmetrically equipped with bearing seats 5 at both ends. A support rod 51 is symmetrically installed between the two bearing seats 5 on any side. A first gear shaft 53 is installed on the support rod 51 through a fastener 52. The fastener 52 is in sliding fit with the support rod 51. The fastener 52 is connected to the end of the C-shaped plate 253. Two lead screws 54 are symmetrically installed between the two main square tubes 21. The two lead screws 54 are arranged parallel to each other on both sides of the first gear shaft 53 and mesh with it. The threads of the lead screws 54 have opposite directions on both sides with the center line as the dividing line. A control motor 55 for driving the lead screws 54 to rotate is fixedly installed on the outside of the main square tubes 21. (Refer to...) Figure 1 The two control motors 55 on the same side are located on the outer wall of the main square tube 21 at different positions, and the two control motors 55 on the same side are controlled by the same controller or driver to start and stop. Taking a multi-axis motion controller (such as a high-performance motion controller based on DSP or FPGA) as an example, it can be paired with dual-channel or multi-channel motor drivers. The motion controller directly sends identical control signals to the two motor drivers, including start, stop commands, and speed command signals. Since the two controlled motors 55 receive the same control signals, they can achieve synchronous start, synchronous stop, and the same speed, with controllable rotation direction, provided that the motor parameters are the same. The specific principle will not be elaborated in this embodiment; refer to the operating principle of existing multi-axis motion controllers. When the two control motors 5 start synchronously (both have the same speed and direction of rotation), they simultaneously drive the lead screw 54 to rotate. After the two lead screws 54 rotate in the same direction, their external threads will intermittently press against the outer thread of the first gear shaft 53, causing the first gear shaft 53 to... Figure 6 As shown, the linear extrusion force in the M direction causes the first gear shaft 53 to drive the two fixed parts 52 to slide relative to each other on the support rod 51 (i.e., the distance between the two fixed parts 52 on the same support rod 51 increases or decreases). After the fixed parts 52 move, they drive the synchronizing block 252 through the C-shaped plate 253, thereby realizing the electronic control effect of the distance between the two U-shaped steel blocks 3, making the change of the distance between the U-shaped steel blocks 3 more convenient and precise.
[0021] See Figures 1-6 In another embodiment, an I-beam 33 is slidably installed in any of the convex grooves 31. Square holes 331 are equally spaced on the opposite surfaces of the I-beam 33 along its path. Locking bolts 34 for positioning are provided on the I-beam 33. In the initial state, the two I-beams 33 on the same U-shaped steel block 3 are installed in the same position (i.e., they overlap each other from a top view). The square holes 331 at the higher position (larger horizontal height) and the square holes 331 at the lower position (smaller horizontal height) on the two I-beams 33 overlap each other at the same time. At this time, the diameter of the steel wire that can pass through the square holes 331 is the largest. Within the same U-shaped steel block 3, two I-beams 33 facing each other and near their ends are provided with equidistant synchronous gear blocks 35. A synchronous gear 36 meshes between the two synchronous gear blocks 35 on the same side. The synchronous gear 36 is fixed to the inside of the U-shaped steel block 3 via a positioning shaft. In actual operation, the I-beams 33 can be adjusted by loosening the locking bolts 34. When one I-beam 33 slides in the convex groove 31, the synchronous gear block 35 on the inside of the I-beam 33 at that position will drive the synchronous gear 36 to rotate. The rotated synchronous gear 36 then drives the other I-beam 33 to slide in the convex groove 31. The sliding directions of the two I-beams 33 relative to the convex groove 31 are opposite. Therefore, compared to the initial state, the square holes 331 on the two I-beams 33 change from a fully overlapping state to a partially overlapping state, which allows for the reduction of the diameter of the reinforcing bars, thereby satisfying the positioning and fixing of reinforcing bars of different sizes, and further improving the applicability.
[0022] In this design, a silicone fin is embedded in the center of the inner wall of the square hole 331. When the reinforcing steel skeleton enters the overlapping area inside the square hole 331, the two sides of the reinforcing steel skeleton will contact and slide down relative to the silicone fin. The silicone fin can wipe the reinforcing steel skeleton in this area. At the same time, the silicone fin shrinks and adheres to the square hole 331 under the pressure, providing a flexible foundation for the contact area of the reinforcing steel skeleton and reducing the wear and tear on the reinforcing steel skeleton. Furthermore, such as Figure 4 As shown, a roller 321 is installed on the inner side of the limiting groove 32, and the outer ring of the roller 321 is in contact with but not connected to the inner wall of the I-beam 33. At this time, the two sides of the steel reinforcement skeleton do not enter the limiting groove 32. The roller 321 in the limiting groove 32 supports the outer wall of the I-beam 33 and provides rolling friction, reducing the sliding loss of the I-beam 33 relative to the convex groove 31.
[0023] In another embodiment, see Figures 1-6 As shown, the fixing member 52 includes a displacement seat 521 slidably mounted on the support rod 51. A second gear shaft 523 is installed inside the displacement seat 521 through a sleeve, and the second gear shaft 523 is concentrically fixedly connected to the first gear shaft 53. In this embodiment, the two lead screws 54 can be controlled to rotate in the same direction but in different directions by the control motor 55. At this time, the two lead screws 54 apply opposite compressive forces to the first gear shaft 53, so that the first gear shaft 53 is subjected to such... Figure 6 The axial compressive force in the N direction, as shown, causes the first gear shaft 53 to rotate about its own center line as the axis. An adjusting frame 522 is inserted into the displacement seat 521. A linkage tooth block 524 is provided on the inner side wall of the adjusting frame 522, and the linkage tooth block 524 meshes with the second gear shaft 523. A connecting rod 525 is fixedly installed on the upper end face of the adjusting frame 522, and the end of the connecting rod 525 is fixed to the lower end face of the I-beam plate 33. When the first gear shaft 53 rotates, it synchronously drives the second gear shaft 523 to rotate in the sleeve. After the second gear shaft 523 rotates, it gradually meshes with the linkage tooth block 524, thereby driving the adjusting frame 522 to move laterally on the displacement seat 521. After the adjusting frame 522 moves, it drives the connecting rod 525 to move synchronously. After the moving connecting rod 525 moves, it drives the I-beam plate 33 to move, thereby realizing the adjustment of the overlapping area of the square hole 331 on the I-beam plate 33. This method can realize the adjustment of the positioning size at different positions by changing the forward and reverse rotation of the same drive source (i.e., the control motor 55), which has higher control accuracy and further improves the convenience of adjustment. Under normal conditions, both I-beams 33 are located in the center of the convex groove 31. When the overlapping area of the square hole 331 is changed by controlling the motor 55, since the two I-beams 33 move synchronously, the center line (along the vertical direction) of the overlapping area of the square hole 331 does not change. That is, when the adjustment is completed and production is switched, the fabric grabbing robot can put the steel skeleton of another size into the overlapping area of the square hole 331 according to the insertion program of the previous size steel skeleton. That is, the grabbing and insertion program of the fabric grabbing robot does not need to be changed, and its adaptability is stronger.
